DomainKeys Identified Mail (DKIM) defines a mechanism by which email messages can be cryptographically signed,
permitting a signing domain to claim responsibility for the introduction of a message into the mail stream.
Message recipients can verify the signature by querying the signer's domain directly to retrieve the appropriate
public key, and thereby confirm that the message was attested to by a party in possession of the private key for the signing domain.
This is the list of DKIM selector configured for DKIM signing. Each domain can have multiple selectors.
Double clicking a domain opens the DKIM selector editor.
Right click one or more selected domains to choose to disable or delete the DKIM selectors.
